ATTACHMENT TO SALT-GRAINERS.

SPECIFICATION forming part of Letters Patent No. 321,345, dated. June 30, 1885.

Application filed February 18, 1885. (No model.)

To ail whom, it may concern:

Be it known that I, JOSEPH GUSSONpf Bay City, in the county of Bay and State of Michigan, have invented new and useful Improvements in Salt-Grainers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in attachments to saltgrainers; and the invention consists in so constructing and operating scrapers employed for the purpose of automatically scraping the salt 1 5 as deposited in the grainers, where such deposit is induced by the operation of circulating steam through the pipes running through said grainers and just above their bottoms, which will scrape the salt from underneath such steampipes as well as from the more exposed portions of the grainer. There are various mechanical devices employed for scraping the salt from one end of the grainer to the other,. and thence out upon an inclined way, which scrape the exposed portions of the bottom, and also take the salt which maybe deposited on the tops of the pipes, allowing, however, a ridge of salt to gradually accrete below said pipes, which accretion must be removed by hand frequently, or the proper circulation of the brine through the grainer is obstructed and the salt generally damaged in color.

Figure 1 is a perspective View of a grainer, showing myimproved attachment as connected with rotary scrapers. Fig. 2 is an enlarged elevation showing more clearly the construe tion of such attachment.

In the accompanying drawings, which form a part of this specification,A representsasalt- 4o grainer which is provided with a system of steam-pipes, B, as in the usual construction of such devices, and having at one end an inclined table, 0, which leads to the drainingboard. At each side of the grainer, and at a suitable distance above the same, I secure the horizontal ways D, terminating at one end in inclined ways E, which are of the same pitch as that of the inclined table 0. Journaled in proper bearings at this end of the grainer is a shaft, F, which carries near each end thereof a pulley, groove, or sprocket-wheel, G, around which endless cables or chains H pass to and around a similar pair of wheels, I, upon the shaft K, journaled in boxes upon the upper ends of the standards J. In the drawings these devices are shown as upon one side of the grainer, but it should be understood that the duplicate of them are upon the opposite side also, both working in unison and harmony.

O are risers secured to the sides of the grain- 6o er at or near the foot of the inclined ways E. J ournaled upon stub-shafts projecting inward- 1y from these risers are the grooved pulleys P, beneath which the rope orendless chain travels, the intention of these pulleys being merely to compel. the chains carrying the scrapers to travel in a horizontal plane along the length of the ways D.

Upon the top of the standards Jand O I se cu re the inclined ways R. S is a cross-bar or rod secured at its ends to the cables or chains H, and upon this rodthe scraper T is pivotally secured. This scraper consists of a suitable number of triangular frames, a, pivotally secured at one of their corners upon the bar S, and at one of the other corners there is secured the bar scrapenplate V by means of hangers b, pivotally secured tothe shaft XV; and the outer or lower edge of this scraper-plate is notched, so as to straddle the steam-pipes in the bottom of the grainer, and upon each end of the rods S and XV are secured the wheels X,

adapted to travel upon the ways R and D. Pivotally secured to the front, and near the upper edge of the scraper V, are the lovers 0 and d, the upper ends of the former being also pivotally secured to a bar, E,while the latter are in like manner secured to a bar, F, while the lower ends of these levers ed are pivotally secured to small scrapers 71.,which are thus alternately connected to the bars E and F. The latter are adapted to have a reciprocating motion,which,being given in opposite directions to each of the bars, forces the lower portion of these small scrapers h, which are notched in their upper edge for that purpose, to projectbeneath the pipes B, and in their travel remove the salt from under such pipes. As the scraper V starts from the foot of the grainer opposite the inclined way 0, the ends of these [00 bars E F are brought into contact with suitable buttons, 1 which compel each of these bars to move in opposite directions, and as the scrapers arrive near the end of the grainer, which terminates in the inclined way G,other stops, k, are arranged to reverse the position of the bars E F,thereby withdrawing the projecting portions of the small scrapers h from beneath the pipes.

In practice motion is communicated to the shaft F from any convenient power, causing the chains to move slowly and dragthe scraper through the grainers, producing an agitation of the brine, and gathering all the salt that has been precipitated from underneath the pipes as well as from the more exposed portions of the bottom of such grainer. In the continued movement of the parts the scraper is compelled to travel up the inclined table, deposit the collected saltupon the draining-board, and thence the scraper passes on, following the change of the direction in the run of the chains. down the upper inclined ways. In this return movement the scraper-blade is projecting upwardly. In the further travel of the parts the frames at of the scraper strike the deflecting portion m of the ways D, which causes the scraper to reverse its position, the wheels carrying the same following the curve of this portion of the ways, down which they slide or roll until they rest upon the horizontal portion of such ways to resume their travel toward the inclined end of the grainers.

Although this improvement is shown as attached to a scraper actuated by a rotary motion, it will readily be seen that the same improvement may be attached to scrapers car ried by a reciprocating motion,'and such I deem to be within the scope of my invention.

\Vhat I claim as my invention is 1. In combination with a salt-grainer having a system of steam-pipes therein, and with a scraper adapted to remove the salt from the bottom of such grainer, a series of scrapers adapted -to be projected beneath the stean1- pipes,and be withdrawn therefrom laterally, substantially as and for the purposes described.

2. The combination, in a salt-grainer having steam-pi pes, and with a scraper adapted to remove the salt from such grainer, a series of small scrapers arranged in pairs,and adapted to be projected under the steam-pipes, and removed therefrom by the reciprocal action of two bars, one above the other, such reciprocation being in opposite directions and connected with such small scrapers by the pivoted levers, substantially as and for the purposes specified.

3. The combinatiomwith a salt-grainer having steam-pipes,of the notched scraper adapted to straddle the steam-pipes, with a series of small scrapers pivotally secured to such main scraper and actuated by stops 7: and 70 through the bars E F, and the levers con necting such bars with such small scrapers, substantially as and for the purposes set forth.
